Figure 1-13: Device C, connected to port 2, transmits a packet for
device A. The bridge learns the address of device C and
recognizes the address of device A, so it forwards the packet to
port 1.
Figure 1-13 Learns C, Forwards Packet
Figure 1-14: Device D, connected to port 2, transmits a packet for
device C. The bridge learns the address of device D and
recognizes the address of device C is on the same address list, so
it filters the packet.

The bridge can now effectively control network traffic by
forwarding packets only to relevant network segments.
